HeartSpot: Privatized and Explainable Data Compression for Cardiomegaly Detection

1 code implementation5 Oct 2022 Elvin Johnson, Shreshta Mohan, Alex Gaudio, Asim Smailagic, Christos Faloutsos, Aurélio Campilho

HeartSpot priors are ante-hoc explainable and give a human-interpretable image of the preserved spatial features that clearly outlines the heart.

Enhancement of Retinal Fundus Images via Pixel Color Amplification

1 code implementation28 Jul 2020 Alex Gaudio, Asim Smailagic, Aurélio Campilho

We propose a pixel color amplification theory and family of enhancement methods to facilitate segmentation tasks on retinal images.

Lung cancer is the deadliest type of cancer worldwide and late detection is the major factor for the low survival rate of patients.

Did you miss it? Automatic lung nodule detection combined with gaze information improves radiologists' screening performance

no code implementations9 Oct 2019 Guilherme Aresta, Carlos Ferreira, João Pedrosa, Teresa Araújo, João Rebelo, Eduardo Negrão, Margarida Morgado, Filipe Alves, António Cunha, Isabel Ramos, Aurélio Campilho

Likewise, combining the findings of radiologist with the detection algorithm only for low fixation regions still significantly improves the detection sensitivity without increasing the number of false-positives.

Data-Driven Color Augmentation Techniques for Deep Skin Image Analysis

no code implementations10 Mar 2017 Adrian Galdran, Aitor Alvarez-Gila, Maria Ines Meyer, Cristina L. Saratxaga, Teresa Araújo, Estibaliz Garrote, Guilherme Aresta, Pedro Costa, A. M. Mendonça, Aurélio Campilho

Specifically, we apply the \emph{shades of gray} color constancy technique to color-normalize the entire training set of images, while retaining the estimated illuminants.
